Why Analog Rails

Analog Rails is a complete analog expert system that is intended to reduce the
time to market on your mixed signal chips by a huge factor. There is a
methodology and flow built into it. The usage is a paradigm shift and is
several generations beyond what is out in the market.

REDUCE CYCLE TIMES

Because of layout automation, real parasitics are used during the design
phase.

Last minute changes? No problem. Blow away the autoroutes, edit, then
autoroute again.

Place your DUT into your already established test benches (we can supply
them), change the spec, and run the optimizer. Saves weeks of trading off
between specs and operating regions (set minimum vds-vdsat).

Displays changes on hierarchies below by colorizing the hierarchical editor

SAVE AREA

No need to be conservative on layouts. Legacy blocks are designed with 20%
area thrown away to leave room for design changes. No longer needed.

The circuit designer can utilize black space during the design and make
sizes bigger for matching or increasing headroom. The designer can also
tradeoff sizes (rout vs gm) for layout efficiency.

Sensitivity analysis based on the REAL layout parasitics can allow the
circuit designer to be less conservative on sizes.

Top down layouts freeze the size of lower blocks, Now you can quickly
change the lower cells and readjust the top level blocks.

Can flatten layout hierarchies, because we keep the intelligence (cross-probing, hierarchical net names, etc). You can squeeze devices together.

IMPROVE QUALITY

Your layout designer has no chance against our automatic router. Our router
is electrically aware. We know which nets are high impedence, low impedence,
static, dynamic, etc. The router gets information from the simulation run
automatically. Our router will keep capacitances low when needed, shield
differential or sensitive nets, etc.

The circuit designer controls the location of the devices at the rate of 30
seconds per device, or can save time by running "mimic layout", which places devices down in a similar manner to the user selected design.

Automatic built-in inter-digitized or side by side differential structures
with perfectly symmetrical routing.

Sensitivity analysis provides bullet proof designs.

Reduced cycle time results in more verification time. No more last minute
scrambling and taking shortcuts.

COMPATIBILITY

REDUCE CAD EFFORT

Tools all work together. Analog Rails is a complete designers package. No customization required.

The "It's So Easy, An Analog Circuit Designer Can Do It" PDK GUI puts the design group in complete control.

Built in Design and Data management will work with any backend version control system, but the user gets to see changes elegantly within the tool. Because we work within our source code, our system is better. We didn't throw DM over the wall to 3rd party vendors. We took responsibility (think of Windows relying on 3rd party vendors to handle anti-virus, as opposed to the built in security of Unix/Linux)
